Ive just tested alkalinity twice and i got a reading of 130ppms ?? that seems a little crazy ..i read the instruction leaflet and it says anthing over 120ppms is bad and to consult your lfs ...so i thought i would ask you guys and gals for some advice on lowering it (bi carb soda ) or will bi carb raise it, im a little confused on whats going on.
all other readings were as follows
ph-8.2
ca- 450ppms
p04- 0
no2-0
n03-0
nh4-0
salinity 1.028 ( ive added some fresh will test later for change)
cheers
